The 400V low-voltage cable branch box is mainly used in urban residential areas, industrial zones, industrial and mining enterprises, high-rise buildings and other three-phase AC 380/220V, 50Hz, rated current 630A and below power systems. It is used as a power protection box for cable trunk network branch wiring and control and protection of branch lines. In use, there can be up to 6-8 branch incoming and outgoing lines, which can achieve multi-channel power transmission in the community, providing technical support for deepening the load center, shortening the power supply radius, and reducing line losses.
The DFW type AC low-voltage power cabinet produced by our company complies with standards such as GB7251.5 “Low voltage switchgear and control equipment – Part 5- Power distribution equipment for public power grids”.
